I am just speaking from what I have seen...I ride with four guys..1 '08 96..2 '09 96 and a 10 limited 103...all bikes are Ultras and only have pipes and air cleaner upgrades no tuners and all the bikes run almost identical..you sure couldn't pick the 103 out of the pack...Yes I have rode them all several times and the seat of my pants dyno can not tell either.
*************************
A simple to install Tuner on these bikes Like a TFI Would of Made the Seat of the Pants IMPROVEMENT.... No Stage One on the 96" or 103" will show that much MORE improvement With Out More fuel.
NO added fuel is like putting on size 9 boots when you need size 10's
The TFI or other fueler Does Make That difference.. BIG seat of the pants.
ALL HD's are TOO Lean from HD and that is that.(EPA) Then We modify the exhaust and intake so it BREATHS more air ,,,,, But where is the GAS? Sure the Brain puts out More fuel with the air But too lean and doing BOTH improvements Even HD says One Or the Other....NOT BOTH..
Now if you go into HD and have the map up-grade or what ever it is called and Yes you get a Little more Fuel........plus More Redline of which YOU DON"T NEED, with the Longer stroke(4.375) and smaller piston of the new bikes but ending up still Too Lean.
Yes HD has a cure for 550$ plus dyno time..... I would do my own and install a TFI with our forums Discount taken and any other you Qualify for.... You will have a great Running Street/Travel bike and for Less $$$..
If you are wanting the 96" to lightly modify and go 103" after 50,000 miles later, That IS a good plan ALSO... BUT then there is the Cam and Head thing Again......... POWER,,,, It Will Never End with me I know..
